Motorists travelling near the Collooney roundabout in County Sligo are urged to drive with caution this morning after an articulated truck overturned onto its side.
The Fire Service says the outbound lane from Sligo is reduced to one lane and the inbound lane to Sligo is closed completely.
Gardai say it will be a number of hours before the lanes will reopen.
Also, the road between Collooney and Ballisodare is blocked as a result of a truck becoming stuck under a bridge.
Diversions are through Ballygawley and Carraroe.
A truck has also gone off the road in the Barnesmore Gap in Donegal.
